This is quite the water project. The little holes with water coming out were really quite delightful and I guess to be expected from what I read. "The wooden 12 foot diameter Toketee Pipeline is passed, which diverts much of the volume of the North Umpqua River to a powerhouse downstream. This artificial taming of the river allows the waterfall to flow in an extremely consistent manor all year long." See picture 3 for more details.
